Erasmus son CLNING oUTsEwna CATCH-Basura To all whom t may concern.'

Be it known that I, JAMES Nrsn'r, a citi- Pawtucket, in the county of Providence, State of Rhode Island, have invented a'certam new andusetul Improvement inAppallatus 'forl Cleaning Out Sewer Catch-Basins, of which the following is a speclficatlon, referencc being'had therein to the accompanying drawings. I y The invention provides a practical-apparatusfor expeditiously and economically` cleaning out sewer catclifbasins, it comprising portable cleaning-out 'mechanism 1ncludingpower-driven mechanism all mounted upon a self-propelling vehicle-truck hav' inge-dumping body and adapted to travel and shovels the muck, sand and `rubbish into buckets which are lowered by hand into the catch-basin and when filled are hoisted by hand and emptied by-hand into a cart or upon the adjacent roadway. The work is unpleasant andv unhealthful, since the laborer lwho descends into the. catch-basin has to stand in a bad-smelling unwholesome mass, the llatter usually submerged under lmore or less filth-charged lwater, and more or less of the water, mud, and other contents of the bucket that is being withdrawn from the catch-basin splashes or falls upon' him. The work of shoveling the heav)r wet contents of the catch-basin is very laborious. Not only is the weight of the watercharged successive shovelfuls considerable, but in addition the suction which has to be overcome in lifti fr each shovelful requires the exercise of con. iderable strength to overcome it. Sometimes, the mud or the like is -dug out and withdrawn Vby means of hoes or similar implements in the hands of a workman standingon the sidewalk above the catch-basin, which is a slow operation'. Both of the modes of clearing out 'a catchbasin which have just been referred to are specmeuon of'retters latent. Patented Sept. 23, 1919. Application tiled Novemberd?, 1915. Serial No. 62,046. l

slow and expensive, and are inadequate tlmes-of emergency, as when a storm washes unusual quantities of material into the I catch-basins of a city or town. lVhen this happens at present. the prompt cleaning out of a system -of catch-basins necessitates the employment of a largenumber of laborers and heavy expense. Unless a' large force is set to..wo1k, the choked-up condition of some of the catch-basins continues for an indefinite period of time,l with liability to damage Ito roadways and property owing to the inability of surface water to escape through the catch-basin into the sewers in case of another rainfall. f. v

The apparatus in which the invention resides, designed for the work of cleaningr out sewer `catch-basins, comprises a self-propel- -ling vehicle, a dumping body or the like receptacle in connect1on with such 'vehicle designed to /reeeive the spoil taken from a catch-basin, an orange-peelv or the 'like dredging bucket of the required small size and proportions adapted to be passed through the manhole at the top of a catch- Ibasin, means for lowering and raising the bucket by power at the will of the operator and enabling it to be swung about within the catch basin by an operator and causedto act at any desired point `in the lower part of the latter, means for closing and opening the bucket at the will of an operator. and a vmovable crane for enabling the .bucket to be swung into position to enter the manhole or into a position over the dumping' body, and vice versa.

The drawings 'show an illustrative ernbodiment of my'invention, which I will now describe.

Figure 1 of the drawings shows the apparatus aforesaid in perspective and re re- 'scnts it as standing alongside the man ole of a catch-basin.

Fig. 2 is a detail view showing the locking device for the crane to keep the latter from swinging. The selfpropelling vehicle shown in the drawings comprises a truck mounted upon strong wheels l, 1, having heavy and substantial tires 2, 2of the character provided for vehicles required to carry heavyloads, the engine being'located within the hood 3 and the steerin apparatus being shown at 4 conveniently a jacent the drivers seat 5. The rear part of the vehicle carries the er;y

provide tordumping.

wagon-body (3, of proper construction to Intermediate the drivers seat 5 andthe dumping body 6 is located the power-equipment for working the dredging bucket 7 and in this case'also `crane 10 tlnt is mounted `upon the vehicle,

and after passing partly'around the sheave or pulley 7" passes vto and partly around a second sheave or pulley 7c, the 4latter l0- cated approximately in line with the upright shaft or mast. 10l ot the crane,v and from the said pulley or sheave 7 c the said cable passes downward and tinally is connected 4to the windlass located between the drivers seat 5 and the body 6 and forming a part of the power mechanism. The gearing of such windlass is shown in Fig. 1. The said windlass is arranged to beoperated by-power at the will of an operator in vany of the usual modes so as to cause it to turn'in order to wind up the cable to raise the bucket, or un-f Wind the cable to lower the` bucket, or to re.- main at rest.l The upright shaft or mast 10'A of the crane l() is mounted suitably in bearings 10", 10, in connection with the vehicle and adjacent the body 6. Provisionsof usual character are supplied in connection with the bucket 7 for the purpose of automatically closing and opening the bucket'at the will of the operator. In the present instance these provisions -include hose-pipes. 11,v 11, leading from 4the bucket to a hydraulic pressure apparatus, the controlling devices of which are indicated at 12. Thus in this instance the bucket itself-is opened and closed by mea-ns of hydraulic pressure transmitted at the will of the operator by means of oil contained within the hose-pipes 11, 11.

A catch-'basin manhole 13 is shown open or uncovered, and the apparatus 1s shown -locatcd alongside the curbing of the s1de walk adjacent the said man-hole, with the' arm of the crane swung outboard and bucket 7 elevated above the man-hole. The bucket is of quite small dimensions such as to enable it in a closed state to pass down through the man-hole and to =he withdrawn subsequently through the man-hole with the load it hastaken up. After having been lowered in a c losed condition through the man-hole by causing or permitting the hoist to pay out. eable,.the bucket is caused -to open, and

hole, and then the bucket is raised high:

enough to permit it to be swung inboard over the bod)- 6. It 1s thus swung and the vpressure. devices are operated to cause the `bucket to open and discharge into the body. The operation having been continued until the, catch-basin is properly emptied` the apparatus is caused to travel under its own propelling power to the next. catch-basin to be cleaned, or, when the body 6 is filled, to the dumping ground, at which latter place the contents of t-he body 6 are dumped, and the vehicle is caused to run to the next catchbasin to be taken in hand. A

lt is intended that in the use of the apparatus at: a catch-basin the boom of the crane shall be swung outward from the body G into an outstanding position in which its free extremity extends above the man-hole, so that the bucket in being lowered shall descend vertically into and through the manhole and subsequently in being raised shall rise vertically out through the man-hole. The outward movenient of the boom into 'the desired position may be occasioned by one of the workmen employed in connection with the apparatus, as for instance by the one who stands at the man-hole to manipulate,

the bucket, and who may for the. purpose pull outward upon the hose-lengths 11, 1'1. 0r the crane may be h ung in manner to cause it to tend to swing outward of itself. Usually, however, in the employment of the apparatus the wheels at the side of the truck nearer the man-hole are lower than thoseat the other side, in consequence of the custo mary curvature or inclination ofv the roadway from the middle of its width toward either side, or in consequence of. the said wheels restingr in the depression or hollow of the gutter. Consequently/. the boom will tend to swing outward without special provision therefor. For the purpose ot arresting the boom in proper position with reference to the man-hole, and so as to render unnecessary the intervention of one of the workmen for the purpose` I provide a checking chain or rope 15 which extends from some convenient point of attachment at the tar side of the body to the boom, and is of the proper adjusted length to arrest the outward movement ot the boom when its end is in position over the man-hole. To provide for adjustment ot' the outward movement of the boom, the chain islngnged atditiferent malossi. t@
